Title:

PHENYL ETHER DERIVATIVE

Document Type and Number:

Japanese Patent JPH01246250

Kind Code:

A

Abstract:

NEW MATERIAL:A compound shown by formula l (Z is CX or N; X is H or halogen ; R is lower alkyl).

EXAMPLE: Methyl 3-(2-chloro-4-trifluoromethylphenoxy)benzohydroximate.

USE: A synthetic intermediate of herbicides and capable of introducing diphenyl ethers showing high activity with a small amount, having a wide herbicidal spectrum and excellent selectivity for main crops.

PREPARATION: A 3-(substituted aryloxy)thiobenzoic acid O-alkyl ester derivative shown by formula II is reacted with a hydroxylamine shown by the formula NH2OH in an organic solvent (e. g., methanol) under cooling with ice-at 200°C for 5 minutes-10 days to give a compound shown by formula I. The amount of the hydroxylamine in the reaction is 1-5mols based on a mol compound shown by the formula II.
